POULTRY-BROODERL SPECIFICATION forming part of Letters Patent N 0.647,778, dated April 17, 1900.

Application filed July 17,1899. Serial No. 724,031. (No model.)

To all whont it may concern/.2

Be it known that I, ALEXIS S. WHITNEY, of Gouverneur, in the county ofSt. Lawrence, in the State of New York, have invented new and usefulImprovements in Poultry-Brooders, of which the following, taken-inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to the class of appa- 1o ratus which are employedfor taking care of and raising young broods of fowl.

The object of the invention is to provide an apparatus which shall besimple and inexpensive in construction and convenient, efiicient,

and safe inits operation; and to that end the invention consists in thenovel construction and combination of the component parts of theapparatus hereinafter described, and set forth in the claims.

The invention is fully illustrated in the annexed drawings, in which 1,

Figure 1 is a perspective View of the brooding apparatus.

View of the same with one-half of the top removed. Fig. 3 is a verticaltransverse section on line Y Y in Fig. 2 with the hinged section of thetop open. Fig. 4 is a vertical longitudinal section on line X X in Fig.3 with the top closed, and Fig. 5 is a rear ele- 0 vation of theapparatus.

Similar letters of reference indicate corresponding parts.

A represents the case or'housing for inclos ing the brood and means forcaring for the same.

B denotes the floor, which extends across the entire interior of thecase A and is placed at a proper distance from the base thereof to forma basement 0 for protecting said floor from moisture and from theefifects of the temperature at the exterior of the case. In thisbasement, preferably at the center of the rear portion thereof, is aheating-chamber D, formed by a wall (1, extending through the basement,parallel with the rear wall thereof, and by transverse wall'sb 12,extending across the space between said walls, thus forming at the sametime two compartments 00, respectively, at opposite sides of theheating- So chamber D, in which is placed a lampZ or other suitableheater.

Fig. 2 is an enlarged plan' The purposes of the compartments 0 O arefirst to confine the heat within the limited area of the chamber D andto serve as moderators or controllers of the currents of air which passthrough said compartments and into the heating-chamber D to supply thelamps with the requisite air for combustion of the flame. Thiscontrolling of said currents of air is effected by means ofinductionports 0 c in the end walls of the case A and by smallerair-diffusing apertures 61 d in the transverse walls I) b, which latterapertures control the passages pf air to the chamber D, so as to checkthe currents suiiiciently to prevent their extinguishing the flame ofthe lamp Z.

The chamber D is provided with a door e to afford access to the lamp.

The floor B is provided with an opening directly over the lamp Z, and insaid opening is secured a metal thimble t, as more clearly shown in Fig.4: of the drawings. This thimble projects above the floor B and hasfitted to its exterior a vertical cylinder 9. To the upper portion ofsaid cylinder are attached pipes h h, which extend divergingly therefrom and toward the main portion of the chamber F above the floor B, inwhich chamber the young brood is confined.

To the free ends of the pipes h 7b is attached a horizontal drum i,which extends through the greater portion of the length of the chamher Fand has connected to it the vent or exit pipe j, extending through thestationary section of the top 11, the companion section at of which ishinged or otherwise removable to afford convenient access to theinterior of the chamber F. The thimble t is secured closely to the underside of the bottom B, and the Ma denote ventilating-apertures in theWalls of the brood-chamber F, and u u are dampers or shutters foropening and closing said apertures, as may be found necessary.
